HelloPharmacist Scorecard of Thyroid Support Vanilla Flavor by TerraVita

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (0.13 mL) without saying how much of each component you get.

This liquid formula has 3 active ingredients, each as a glycerite extract — a form where the herb is soaked in glycerin to pull out the active compounds. Bugleweed, motherwort, and lemon balm are traditional botanicals that have been used to support thyroid and nervous system health.

The product also contains glycerin (the extraction base) and vanilla flavor.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Support for mild overactive thyroid symptoms.
  • We looked for evidence on: Hyperthyroidism, Anxiety, Insomnia, Arrhythmia, Stress, Menopausal symptoms — and 3 related terms.
  • The strongest evidence on file: Lemon Balm is rated "Possibly Effective" for Stress (Natural Medicines).
  • Also on file: Motherwort is rated "Insufficient Reliable Evidence To Rate" for Anxiety, Arrhythmia, Hyperthyroidism, Insomnia, and more.
  • Also on file: Bugleweed is rated "Insufficient Reliable Evidence To Rate" for Hyperthyroidism.

The evidence for these ingredients is mixed and limited. Bugleweed has insufficient reliable evidence to rate for hyperthyroidism, insomnia, and PMS.

Motherwort is possibly effective for bleeding, but evidence is insufficient for alcohol use disorder, amenorrhea, anxiety, and asthma. Lemon balm has possibly effective evidence for cold sores, stress, and depression.

Overall, solid proof that this formula works for thyroid support specifically isn't established in the data we hold.

The evidence, ingredient by ingredient Bugleweed Motherwort Lemon Balm

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Motherwort and lemon balm are generally well tolerated by healthy adults for short-term use, though long-term safety is not well studied. The most common side effects from motherwort taken by mouth are diarrhea and stomach irritation.

Lemon balm may cause dizziness and sedation in some people, though this doesn't appear to happen more often than with placebo. One case of heart rhythm changes (atrioventricular block) was reported with a multi-ingredient product containing lemon balm, but it's unclear whether lemon balm alone caused it.

Bugleweed should only be used under a healthcare provider's guidance because it may affect thyroid function. Bugleweed is likely unsafe in pregnancy and possibly unsafe while breastfeeding — it may reduce milk production.

Motherwort is likely unsafe in pregnancy due to concerns about stimulating the uterus. Lemon balm has insufficient data for pregnancy but should be used with caution while breastfeeding — talk with your doctor or pharmacist first.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Motherwort, Bugleweed, Lemon Balm.
  • The most serious interaction on file is rated Moderate.
  • For scale: 264 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check your medications against this list before you start: thyroid hormones (levothyroxine, synthetic T3, and others) — both bugleweed and lemon balm may reduce their effects. CNS depressants like sedatives, sleep aids, anti-anxiety drugs, and some pain relievers — motherwort and lemon balm may increase drowsiness.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you take thyroid medication, sedatives, sleep aids, or anxiety drugs, check with your pharmacist or doctor before starting this product. The evidence that it works for thyroid support isn't well established.

Bugleweed and motherwort carry real safety concerns in pregnancy and breastfeeding, so avoid them if you're pregnant, trying to become pregnant, or nursing.

Lemon Balm Glycerite Liquid Extract2 drug types · 264 drugs

Cns Depressants

Theoretically, concomitant use of lemon balm might have additive effects with CNS depressant drugs.
Lemon balm seems to have CNS depressant activity in animals and in humans.

Likelihood Possible Evidence B
Thyroid Hormone

Theoretically, lemon balm might interfere with thyroid hormone replacement therapy.
In vitro, constituents of lemon balm extract bind to thyroid stimulating hormone (TSH), preventing TSH receptor-binding and leading to the inhibition of TSH-stimulated adenylate cyclase activity. In animals, lemon balm extract has been shown to decrease levels of circulating TSH and inhibit thyroid secretion.

Likelihood Possible Evidence D

Thyroid Support Vanilla Flavor by TerraVita: Common Questions

Does Thyroid Support Vanilla Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Thyroid Support Vanilla Flavor has a known interaction with 264 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Thyroid Support Vanilla Flavor contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm on thyroid medication?
Not without checking with your doctor or pharmacist first. Bugleweed and lemon balm may interfere with how your thyroid medication works by blocking its conversion to the active form your body uses.
Is this safe to take while pregnant or breastfeeding?
Bugleweed is likely unsafe during pregnancy and may reduce milk supply while breastfeeding. Motherwort is likely unsafe in pregnancy because it may stimulate the uterus. Lemon balm doesn't have enough safety data for pregnancy, and limited data exists for breastfeeding — talk with your doctor or pharmacist before using while pregnant or nursing.
What are the side effects?
Motherwort may cause diarrhea and stomach irritation when taken by mouth. Lemon balm may cause dizziness and sedation in some people, though these don't appear to happen more often than with placebo. Adverse effects from bugleweed are not documented in our data.
Does this actually work for thyroid problems?
The evidence is limited. Bugleweed, motherwort, and lemon balm all have insufficient reliable evidence for conditions like hyperthyroidism. Lemon balm has possibly effective evidence for stress and depression, but not specifically for thyroid support.
Can I take this with sedatives or sleep aids?
Talk to your pharmacist first. Both motherwort and lemon balm may add to the sedating effects of those drugs, increasing drowsiness.
How long can I safely use this?
Motherwort and lemon balm are generally well tolerated for short-term use, but long-term safety is not well studied. Bugleweed should only be used under a healthcare provider's guidance. Ask your doctor or pharmacist how long is appropriate for you.
